Again, Trump won (ignoring faithless electors) by a count of 306-232, which is 56.88%. Under the Wyoming method, the result would have been 370-280, which is 56.92%. That means that
he would have won by a larger margin had we been using the Wyoming method in 2016. I have an Excel spreadsheet breaking it all down, but after I did the work myself, I realized that it was already done, and then some, on the
wikipedia page for the Wyoming Rule.
Here, I'll post a condensed snippet of the table they have on the page to elaborate the point:

As you can see, in
only 5/22 cases would the Wyoming method have resulted in gains for the defeated party, which means that 77% of the time, the Wyoming method would have bolstered the winning party's lead. Nor is the benefit limited to one party over another.
Overall, the Wyoming method would have had an average swing of only 0.48% (absolute value) per election. And again, 0.48% in terms of the current EC is only the equivalent of 2.6 EVs.
